klipshorn speakers
my son has a pair of klipshorn speakers. i don't know the model name but they are pretty big. he's running a mcintosh mc7300 amp to power them.he's thinking of getting a mc602!! he likes to play his music loud! will he hear a difference with the mc602?? he found a mc602 on ebay for 7.2k! would it be worth the money to buy it???
